Car pressure

The right tyre pressure

Every auto manufacturer selects, tests, and approves various tyres for each model, according to weight performance, size, and other criteria. Load and speed indexes are very important in tyre selection and determine the appropriate air pressure.
The recommended tyre pressure is indicated on the inside of the fuel tank flap, on the inner strip of the driver side door, in the owner's manual, and sometimes in the motor compartment. You can also use our table of standard pressures.
Be aware that there are two recommended tyre pressures for your vehicle: one for travel at maximal vehicle capacity weight or on the highway and one for travel at normal vehicle capacity weight. Tyre pressure should be checked when the tyres are cold. In other words, if your vehicle has been parked for at least two hours and has not been driven more than 1-3 miles since, you will get an accurate tyre pressure reading. If, on the other hand, you stop at a highway rest area and your tyres are not cold, add 0.3 bar to the recommended pressure (1 bar = about 1kg/cm²). Be sure to check the pressure again once the tyres are cold. Never lower pressure if tyres are not cold.
Be sure to reinstall valve caps to insure proper airtightness. Change them when you mount new tyres.

Risks associated with incorrect tyre pressure

Underflation and even slight overheating can lead to a blowout at any moment. Tyre tread will wear faster on the sides and fuel economy will be poor. Your tyre's sidewall may even wear if the underinflation is marked. On the other hand, if the tyre is overinflated, the tread will wear much more quickly in the middle. The tyre will then be more vulnerable if you drive on deformed pavement or debris.
Be sure to check tyre pressure about once a month and if there is a sudden change in temperature. It is also a good idea to inflate the spare tyre to the maximum recommended pressure.
